If a copy of the joc.war file already exists in the archive folder, it will not be overwritten. This ensures that only the original joc.war file is archived and not an already patched one. It also ensures that the patch executor is able to perform a rollback to the original state. This also makes sure, that you can choose which patches to apply at any moment in time, e.g. you have already applied the patches "x", "y" and "z". If you choose to apply only patches "x" and "z" going further you can do so by deleting the patch "y" from the patches folder and simply run the patch executor again.
When a new installation is performed on an existing JOC Cockpit Installation the Setup will clean up the patches- and the archive folder of the previous installation.
